Roman created DRILL-5007:
----------------------------

             Summary: Dynamic UDF lazy-init does not work correctly in multi-node cluster
                 Key: DRILL-5007
                 URL: https://issues.apache.org/jira/browse/DRILL-5007
             Project: Apache Drill
          Issue Type: Bug
          Components: Functions - Drill
    Affects Versions: 1.9.0
            Reporter: Roman
            Assignee: Arina Ielchiieva


When I registered jar in 1st node and ran long query with function for first time I had got error:
{quote}
Error: SYSTEM ERROR: SchemaChangeException: Failure while trying to materialize incoming schema.  Errors:
 
Error in expression at index 0.  Error: Missing function implementation:[f(VARCHAR-OPTIONAL, VARCHAR-OPTIONAL).  Full expression: null..
{quote}
When I tried to run this query second time it finished correctly. It seems another nodes did not get new function. 

So lazy-init does not work well on another nodes before query fails.
